Through at least the next day or so, weak trade winds are expected
over Hawaii with a surface trough in the vicinity and a weak upper
level trough to the north. This will allow for land and sea
breezes to dominate over the islands and clouds and showers to
follow that pattern. Trade winds are forecast to gradually
strengthen through the weekend and into early next week as the
upper trough moves away and the typical Pacific surface high well
north-northeast of the state takes hold again. Thus some windward
and mauka showers with drier leeward areas should become more
common. Some increases in moisture and thus possibly shower
coverage over the islands are possible next week, with a moisture
surge indicated around Monday-Tuesday by model guidance, with the
GFS most aggressive. After that, enhanced moisture with a
potential tropical system around mid-late next week is currently
expected to stay south of Hawaii.
